Temperature is the measure of average kinetic energy of all the atoms and molecules in an object
Because they: * Have mass * Have a speed
kinetic energy
Heat energy
Heat.
It increases. Heat is the kinetic energy of vibrating atoms/molecules.
Kinetic energy
Of particles, such as atoms or molecules.
A loss of kinetic energy in the atoms or molecules of a sample of matter will result in the cooling of the sample. That sample will get colder as remove thermal energy from it. The atoms/molecules of a substance have kinetic energy associated with them. This kinetic energy is the result of atomic and/or molecular motion. As a sample of matter cools, the atoms and/or molecules will lose mobility. Loss of mobility and vibrational energy, which are forms of kinetic energy, will become apparent when thermal energy is removed from the sample.
atoms or molecules
Thermal (heat) energy - which is the kinetic energy of atoms/molecules.
That is called heat energy.
